java - get src attribute inside div tag jsoup -

-

i trying parse html getting nullpointor. want extract image uri below html.

string html = "<div class=\"thumb-box thumb-160\"><a class=\"mimg\" data-id=\"1394085169856_6744\" href=\"#\"><img class=\"thumb\" src=\"http://i.ytimg.com/vi/u7declndzqw/hqdefault.jpg\" style=\"top: -15px;\"><span class=\"btn\"></span></a></div>";  document document = jsoup.parse(html);  element element = document.select("div.thumb-box thumb-160").first();  system.out.println(element.select("img").attr("src")); 

element element = document.select("div.thumb-box thumb-160").first();

you have use . (dot) every class

element element = document.select("div.thumb-box.thumb-160").first();

besides rather straight forward select this

element element = document.select("div.thumb-box.thumb-160:eq(0) a").first();

this yould yet anchor element out of box
